How to solve website pollution? Summary of common causes and treatment methods

for website managers, website pollution is a common problem that affects the normal operation and user experience of the website. At best, it can lead to abnormal page content and ranking decline, and at worst, it may lead to security risks and even be banned by search engines. Many managers are often at a loss when encountering website pollution, and they do not know the root cause of the problem and cannot find an effective solution. This article will comprehensively sort out the common causes of website pollution, dismantle targeted treatment methods, and share daily protection skills to help managers deal with such problems efficiently and ensure the stable operation of the website.

What are the common causes of website pollution?

want to solve the problem of website pollution, we must first clarify the root cause of the problem, the site pollution caused by different incentives, the treatment method is quite different.

1, server security bugs are exploited

the server system or build website program used by some websites has security bugs that have not been fixed in time. Hackers will invade the background of the website through these vulnerabilities, tamper with the page code, implant malicious content, and then cause website pollution. Especially the website using the open source build website program, if the program version is not updated for a long time, the probability of being attacked will be greatly increased.

2, black chain or malicious code implantation

black chain is one of the common incentives for website pollution. Hackers will hide links to illegal websites in the code of website pages. These links are usually not displayed on the page, but will be crawled by search engines, resulting in the website being judged as illegal. In addition, some malicious advertising codes will also force bad content to pop up on the page, causing website pollution.

3, content violations or tampering

if the website itself publishes content that violates search engine rules or cyber security regulations, it will directly cause website pollution; in addition, improper account authority management leads to internal personnel misoperation, or the content is maliciously tampered with after the account is stolen, there will also be abnormal page content.

first of all, the website that has website pollution should be temporarily isolated from other sites of the server to prevent the spread of pollution. At the same time, backup the code and data of the current website in time, which can not only keep the problem sample for troubleshooting, but also avoid data loss caused by subsequent operations.

2, comprehensive investigation of malicious code and black chain

scan the page code with the help of website security detection tools, locate hidden black chains and malicious codes, and delete and clean them one by one. For the tampered page content, it is necessary to restore to the most recent normal version. If the database content is tampered with, it is necessary to use clean backup data for recovery to completely remove the impact of website pollution.

Long-term protection strategies for website pollution

solve the website pollution that has occurred is only the first step, and it is more important to do long-term protection to avoid the recurrence of website pollution problems.

1, regularly update the system and program version

server operating system, build website program and related plug-ins should be kept updated, and known security bugs should be repaired in time to reduce the possibility of website pollution caused by hacking from the root cause. It is recommended to set up version update reminders, check the update situation at least once a week, and give priority to the update of the core program.

2, strengthen account and rights management

strictly control the account permissions in the background of the website, avoid multiple people sharing high-authority accounts, and each account is only assigned the necessary operation permissions. At the same time, set complex login passwords, regularly change passwords, and turn on abnormal login reminders. Once unfamiliar devices are found to log in, immediately lock the account and check the risk to prevent website pollution caused by account theft.

3, install professional safety protection tools

install a professional web application firewall for the website, monitor the access request of the website in real time, intercept malicious attacks and illegal content implantation. At the same time, with the website security scanning tool, regularly conduct comprehensive detection of the website, find latent risk in advance, and eliminate the hidden danger of website pollution in the bud.

4. Sharing of practical skills for website pollution investigation

timely find clues of website pollution, can effectively reduce the impact of the problem, the following are a few practical investigation skills.

1, monitoring search engine inclusion

regularly check the website's indexed pages through the search engine webmaster platform. If unfamiliar illegal pages are found to be indexed, it is likely to be a signal of website pollution. At the same time, pay attention to website ranking changes. If the core keyword ranking suddenly drops sharply, be vigilant about website pollution.

2, check page code and load content

regularly check the source code of the website page, focusing on the head tag, the bottom code area, whether there are unfamiliar links or script code. In addition, pay attention to the page loading when visiting the website. If there is an abnormal pop-up window, jump or content disorder, there is a high probability of website pollution.

To sum up, website pollution is a problem that needs to be prevented in website operation. Its incentives are diverse, and treatment and protection need to be promoted in multiple dimensions. Managers should first clarify the specific incentives for website pollution, and then take corresponding emergency treatment measures. At the same time, establish a long-term protection mechanism and regularly check risks. Only by combining investigation, treatment and protection can we effectively avoid the recurrence of website pollution and ensure the safety, stability and good operation of the website.
